The late, great Professor Norbert Wiener of M.I.T. was the sort of absent-minded genius we referred to in yesterday's tale, and about whom people have been telling stories since the time of Archimedes.
Once a friend stopped Wiener in the street one day and engaged him in conversation. After a few minutes they were ready to part. Said Weiner, with a puzzled look upon his countenance,
"Pardon me, Smith, but when we stopped to converse, in which direction was I walking?"
"Why that was," replied his friend, "Toward Massachusetts Avenue."
"Oh, good," replied Wiener. "In that case I've already had my lunch."
